10 Rules of the road for safe, fun running:

The same held true for running. Not any more. A properly hydrated runner is a healthier runner. Especially older runners who are more susceptible to running injuries. As you age, the blood and oxygen supply to your muscles isn’t as good as when you were in your early 20s. If you are dehydrated during or after a run, it can only aggravate the situation. That’s one reason older runners have more muscle strains, spasms and pulls as they age. They’re dehydrated. Drink up.
